This guide explains how to download and use the mobile app Infomaniak kSync for Android devices (Samsung, Huawei, Google Pixel, etc.) that allows you to synchronize calendars & contacts between Android devices (with data stored at Infomaniak).

Preamble

• Refer to this other guide for an example of using kSync: synchronize an Infomaniak calendar with a Google agenda.

Configure kSync

Prerequisites

1. Download the mobile app Infomaniak kSync (app for Android smartphone or tablet) here:
   
   
    
   • The kSync app is also available on F-droid.
2. Install kSync.

Next:

1. Open kSync from your Android device, a step-by-step assistant will help you configure the app according to your needs.
2. Decide if you want to synchronize tasks.
3. Allow kSync to access the required elements.
4. Allow the app to run in the background for better synchronization (uses more battery).

Once the app is open and pre-configured:

1. Press the button to open the login window to your Infomaniak user account:
   
2. Enter your login information for the user account containing your Infomaniak agenda(s) to synchronize with your Android device.
3. Under the Address Books CARDDAV tab, choose the address book(s) that should appear on your device.
4. Under the Calendars CALDAV tab, choose the calendar(s) that should appear on your device.
5. Start the synchronization with the button located at the bottom right.

Synchronization settings

After pressing the account to synchronize, click on the Settings icon at the top right of the interface to adjust some important settings:

• Synchronization interval: you have the option to modify the frequency of synchronizations (15, 30, 60 minutes, etc.) for each type of information (address books, calendars, tasks).
• Synchronization only via Wifi (and if so, with which networks...).
• Limit of display of past events.
• Color display.
• Display of contact groups.

kSync general settings

Press the back arrow at the top left of the screen to return to the home page.

Press the three horizontal line menu button ☰ then Settings.

Synchronization operation

Once the kSync application is configured, the selected items are automatically synchronized with the Contacts and Calendar applications, installed by default on an Android device.

These applications will allow you to display or hide the address books currently synchronized with Infomaniak:

Synchronization is bidirectional by default, which means that without any particular setting on your part (read below) the modifications made on your phone in this or these new address books and calendars will be reflected in your Infomaniak interface (Calendar and Contacts) and vice versa. Add a contact in the address book currently synchronized with Infomaniak, same for an event on the calendar::

Once added on one side or the other, the information is synchronized at the scheduled interval:

Do not allow modification on the device

It is possible to force read-only via kSync which means that the items are synchronized but cannot be modified by the device.

To do this, on the settings page of the Infomaniak account that interests you, in the Address Books CARDDAV or Calendars CALDAV tab, press the action menu ⋮ to the right of the line of your synchronized items. Check the box "Force read-only":
